my name is Louis, I live in Canada. I am a new member on this forum and I recently bought my first volvo. It's a 1985 Volvo 745 d24t and of course the engine need love. I finished my studies in diesel truck and my goal is to rebuild the engine and run it for several years again (until they ban diesel lol). I have few greenbook service manual for the d24t. I am also planning to swap m46 from a 240 gasser.

I would like to hear all of your personal experience to rebuild the engine and D24 in general. I know it depends of wear, but did you needed to rebore the cylinder with oversize piston or simply new ring set... Doing overhaul, would you suggest me to change everything in new? (crankshaft bearing, valve, connecting rod bearings, etc..)

Good that you have the greenbook. There you will find the specs required for deciding which parts need replacing or overhauled. It is a matter of measurement and inspection. Otherwise how do you know you will need crankshaft bearing, valve, connecting rod bearings, etc.? The bottom end on these engines are usually robust. The more common problems are head warpage from overheating, piston/valve collision from broken timing belt or improper repair (insufficient tightening of crankshaft pulley).

What are the symptoms that make you think you need a complete overhaul? I see lots of black smoke in the first photo, but that might be caused by incorrect IP tuning or timing.

You are probably referring to Photobucket's (successful?) ransom attempt for payment to them to maintain weblinks for photos. Agreed that it's a major impediment. I spent some time trying to find a workaround, got stuck in Github, then gave up for the time being. Supposedly there's a solution for Chrome browser users?

Currently recommend uploading photos directly to D24T.com with the manage attachments option, then insert them into the post via the attachments (paperclip icon) button. IIRC, there's a limit of 5 per post.
